Are Miele 4D bags discontinued?

[tseg]

I noticed Miele 4D bags with smell protectant existed in 2017. I cannot find them anymore. I assume they are discontinued. Did they not work? Any background info on them? I’m about to order new bags and don’t want to miss the opportunity if they still exist.
